Ying Manchuan is born into the body of a descendant of Qin Shi Huang, carrying the Imperial Jade Seal, which can summon heroic spirits from every dynasty. However, as the heroic spirits repeatedly appear beyond his control, he is forced to live in seclusion deep in the mountains. After accidentally entering a battlefield of memories, he discovers how to control the Jade Seal. From then on, accompanied by a group of troublesome legendary generals, he clears battlefields, makes new companions, and eventually resolves the problem of the uncontrolled spirits and reunites with his family, whom he has been separated from for ten years.
